Nigerien yellowcake claim was pulled from a Bush speech last October

There is evidence that there was concern in the C.I.A. about the credibility of the uranium information and that those doubts reached at least some White House officials months before the State of the Union address. Administration officials involved in drafting another speech Mr. Bush gave about Iraq, in Cincinnati on Oct. 7, said that at the C.I.A.'s behest, they had removed any mention of the central piece of intelligence about African uranium � a report about an effort by Iraq to obtain "yellowcake," which contains uranium ore, in Niger. No one has fully explained how, given that early October warning to the White House, a version of the same charge resurfaced in the early drafts of the State of the Union address just three months later, and stayed there, draft after draft.

I guess they must be forgetful types at the White House. If the Nigerien claim was known to be suspect in October how had they managed to forget that by January?
